custom_flutter_chord 1.2.0

Lyrics Chord parser and renderer for Flutter. It also comes with transpose and auto-scroll features.

1.2.0

• Add MinorMode (none / relative / parallel) and the minorMode parameter to LyricsRenderer, replacing the old minorScale behaviour with two correct minor-key conversions applied on top of transposeIncrement:
  • relative: relative minor — chords are left untouched; only the degree reference (number/roman) re-centres a minor third below the major tonic.
  • parallel: parallel minor — each diatonic chord of the major key is mapped to the natural-minor field (I→i, ii→ii°, iii→♭III, IV→iv, V→v, vi→♭VI, vii°→♭VII). Extensions and slash chords are preserved; flat degrees are spelled with flats; chromatic chords are kept unchanged.
• Export ChordNotation, ChordScale and MinorMode from the library barrel.
• minorScale is kept for backwards compatibility (minorMode takes precedence).

1.1.0

• Add keyRoot to LyricsRenderer: when set, the number and roman notations render chords as functional degrees relative to the song key (e.g. in G: G→1/I, C→4/IV, Em→6/vi) instead of the absolute C = 1/I mapping. Degrees stay invariant under transposeIncrement.
• Roman degrees are now quality-aware (uppercase major, lowercase minor, ° diminished, + augmented) and slash chords convert both root and bass.
• Backwards compatible: with keyRoot null the previous absolute mapping is kept.

1.0.2

• Fix chord overlapping when they are too close to each other.
• Add [•] as a visual separator for trailing chords to improve readability.

1.0.0

• Add visual separator for trailing chords to improve readability.
• The separator [•] is automatically inserted between chords at the end of a line or in chord-only lines.
• Add support for multiple chord notations (german, traditionalGerman, french, portuguese, roman, number).
• Fix and improve transposition to minor scale.
